While most elementary teachers experience little difficulty using the decimal system for whole numbers, many do not have the desired depth of understanding for teaching the system. The focus of the material is stage-by-stage creation of a hypothetical numeration system. (MP)

Three board games are presented, with playing directions and comments to the teacher (MNS)

Sample workcards on number operations, patterns of numbers, and algebraic notation are presented to illustrate how a theme in mathematics can be developed. (DT)

Exercises are used when beginning work with calculators to help pupils think about what they are doing. Four worksheets are included, with discussion of their objectives. (MNS)

A method of showing the meaning of decimal fraction without using fraction words or notation. One technique described in detail uses large squares, strips, and small squares; using the metric system and decimal coinage is also suggested. (DT)

Reviewed are the Avon materials and a set of kits for teaching the metric system. (MM)

Rules are given for games (using dominoes) aimed at reinforcing the student's concept of fractions. (DT)

Describes the British primary school approach to mathematics learning. (MM)

Some functions on digits of positive integers are presented as possible sources for useful investigations by students, particularly through the use of calculators and computers or in the writing of small proofs. The material is designed to encourage students to conduct their own investigations. (MP)

Student exploration at a secondary school level of fraction relationships using special graphs is described. (MP)

Using the notion of the difference between a number and its cube as a starting point, this article presents a wide range of mathematical activities at varying levels of sophistication utilizing numerical, intuitive, and graphical approaches. (JJK)
